Application filed February 27, 1922. Serial No. 539,654. 1

ventilator'adapted tobe positioned in the lower rail of a window sash,although not necessarily restricted to this position, as the same may bereadily applied to the upper sash, and also to doors, cars and the like.

Objcctsjofmy invention are to provide a ventilator of the characterdescribed so constructed as to permit a room to be readily.

ventilated without opening the window; to provide improved means forcontrolling the influx of air intothe room; to provide means associatedwith and actuated by control mechanism, the said means being in theform'- "of receptacles adapted to hold medicated material so that theinflux of the air particularly into a sick room will be pure andextremely sanitary. I

A further object of this invention is to provide a device ofthe'character described, which is simple in construction, economical tomanufacture, and which can be readily inserted in the sash of a windowwithout materially altering the construction of the same.

Other objects andadvantages will be ap parent during the courseof thefollowing description. i

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Fig. 1. is a front elevation of the lower end of a window sash havingmyimproved ventilator applied thereto, Y y

Fig. 2 is a transverse sectional view taken on the line 22 of Fig. l, i

Fig. 3 is a horizontal view. taken on, the line 33 of Fig.2, r

Fig. is a detail plan view showing the meansior holding in position thepivoted door of the ventilator, N

Fig. 5 is a rear elevation of the ventilator, Fig. 6 is a modified typeof ventilator, and V v Fig. 7 is another type of ventilator that 7 maybe employed.

In the accompanying drawings wherein preferred embodiment of myinvention, the reference character-A designates an ordinary windowsash,the lower end rail 01* which is provided with a lringitudinalslotoropening 8, which slot extends substan--- tially the entire- Width ofthe lower rail and is adapted to receive therein the ventilating deviceherewith designated as a whole by thenumeral 9. 7

The ventilating device embodies in its'construction a rectangular casingincluding a iorthe purpose of illustration is shown a top wall 10,- abottom wall 11, and side walls 12. This casing is adapted to fit snuglyin the spaceofthe bottom rail that is provided by the opening 8, andinorderthat the descri tion of the osition of the casin with relation tothe sash maybe readily "under stood, the part of the casing thatextendsitlnn the room,as shown n Fig. 1, will be hereinafter referred to as thefront-of,

the ventilating device, while the portion that is positionec ad acentthe outside of the sash,

as shown to advantageinFig. 5, will be re ferred to as the rear of theventilatingdevice. The respective'walls of the, casing terminate at thefront thereof in flanges 13, which flanges pcrmitthe'casing to besecured to the.

bottom rail .J'i, and preferably detachably Adja cent the rear oft-hecasing a screen 15 is secured, by fastening elements 14.

suitably retained by rear "flanges 15"o-f the casing. The purpose ofthis screen is to prevent the entrance ofinsccts or bulky foreign matterinto'thesaid casing.

As shown to advantage in be observed that the flanges 15'-are cutaway inorder to provide'means for the exit of rain water, that may enter theventilating device through the screen and accumulate therein. 7

Adoor 16 is pivotally secured to' the side walls 12Iofthe casing, andthe po ntsof; pivotal contact are preferably oil-center, as

disclosed to advantage in Fig. 2. -This door has mounted adjacent itsupper extremity, on the outside thereof, a handle 17, suitably curved toailord a hand hold not. only for conveniently actuating the door fwhenit is desired to open or. close the ventilating device, but also "topresent a means for readily ralslng the wmdow sash when occasion ,maydemand.

The numeral 18 designates a pair of,

curved extremities, preferably formed integral with the door andpositioned adjacent Fig. '5 it"will til the lower extremity of the same,but disposed on the inside thereof in contra-distinction to the curvedhandle 17. The purpose of these extensions will he hereinafter fullyexplained; V i

As shown to advantage in Figures 2 and at, the top Wall 10 has slots 19formed therein adjacent the'front of the casing, and the portion of thewall between the slots is longitudinally grooved or inwardly bent as at20. 'lhe-purpose of this construction is to have the inwardly 'bentportion 20'con- -vitlrthe top of the door 16 when 1t is. moved from thedotted nneposition to the;

"full line position as shown in Fig. 2. By employingthe slots 19 theportion disposed between-the same will, due to its inherent soi'ingnature, firmly engage the top of the said door, and prevent. itsaccidental displac iient from its closed position.

The numerals 21 and 22 designate receptacles which can eitherbe madeintegral u t3. the side walls 12, can be positioned ad iacent thereto.'l 'hese receptacles are pr. ."lClGCl'WVl-illl hinged doors 23 providedwith extensions lneach of these receptacles, l propose to inserta'iuzantity ot' medicated material such as a-bso; :ent cotton on whichis sprinkled carbolic acid or some suitable sanitary medicinalpreparation. It will be obvious from this construction, that when thedoor of the ventilating device is opened, as shown indotted lineposition in Fig. 2, that the ex ensions-l8 will contact with the doors23 and the receptacles will accordingly he opened.

These said 7 i ed "forms an readily accommodate the various parts'o'fthe device ashetore described, except that the door 16 will be made toconform to the shape of the device use 1 i it is to he understood thatthe form of 'Ihe use or these receptacles my invention, herewith shownand'described is to be taken as a preferred example of the smile, andthat various changes in the shape, size and arrangement of partsmay beresorted to Without departing fromthe spirit otthe invention or thescope 01"- the uhjoined claims.
